Abstract: In this study, the chemical constituents of the three rice varieties were investigated at each of the five stages of grain development using Accurate-Mass Spectrometry (LC-ESI-QTOF-MS/MS). The varieties were: White (Dok Mali105), red (red Dok Mali), and black (Rice Berry) in acidified methanolic extract. Over 80 compounds of the primary and secondary metabolites were tentatively identified.

Abstract: Needs in chemical analysis were considered, for example requirements to “field”, speciation analysis, distribution (local), remote, non-destructive analysis, miniaturization, and automatization. General approaches to analysis were discussed. Search and studies of novel phenomena, regularities and properties of substances which can serve as a basis of new techniques and tools of analysis were noted as significant directions for the future.

Abstract: In the present work eco-friendly, precise, accurate RP-HPLC method has been developed for the determination of gatifloxacin using the concept of hydrotropy. Hydrotropy is a concept of increasing solubility of a solute in water by adding an agent termed as hydrotropes. This concept reduces the use of organic solvents for analysis of drugs which makes analysis eco friendly and less expensive.
